SCALPEL: Semantic Cross-modal Alignment via LLM-Powered Encoder Learning for Medical Vision-Language Representation
Yunzhan Fu, Enyu Bao, Xiangyu Shen +4
The paper introduces SCALPEL, a framework that fine‑tunes a generative medical LLM into an isotropic encoder and uses an asymmetric, anatomy‑negation‑aware contrastive objective to…
Towards Dual-Brain Minimal Sufficient Representation for Vision-Language Navigation
Yihao Wu, Chenyi Xu, Liqi Yan +6
Vision-and-Language Navigation in continuous environments (VLN-CE) requires an agent to ground language in egocentric observations and plan in unseen scenes. Although recent multim…
LongDPM: Overlap-Aware 4D Reconstruction from Long Monocular Videos
Chenyi Xu, Yihao Wu, Liqi Yan +4
Recovering a dynamic 3D scene from a long monocular video is crucial for dense geometry, camera motion, and temporal correspondence to remain consistent in a shared coordinate syst…
DroneSplat: 3D Gaussian Splatting for Robust 3D Reconstruction from In-the-Wild Drone Imagery
Jiadong Tang, Yu Gao, Dianyi Yang +3
Drones have become essential tools for reconstructing wild scenes due to their outstanding maneuverability. Recent advances in radiance field methods have achieved remarkable rende…
